JOHN WOSILTSKI, OF DETROIT, MICHIGAN.

Specification of Letters Patent. Patented Aug. 6, 1918.

Application filed December 21, 1917. Serial No. 208,219.

To all whom it may concern Be it knownqthat I, JonnWosmsKI, a citizen of Russia, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Ship-Protectors, of which the following is a specification.

This invention relates to certain new and useful improvements in ship protectors.

The primary object of the invention is the provision of a protector for ships adapted for preventing missiles from hitting the hull when approaching the same from any side of the ship at. or beneath the waterline.

A further object of the invention is the provision of a protector entirely encircling the hull .of a ship and readily adjustable for positioning adjacent the hull or any desirable distance away from the same, the device presenting only slight resistance to the movement of the ship through the water and being comparatively light in weight.

A still further object of the device is to provide a ship with an encircling missile guard or screen adapted for adjustable positioning from the deck of the ship and being especially serviceable in preventing torpedoes from injuring the hull" of the ship.

In the drawings, forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views,

Flgure 1 is a top plan view of a ship provided with my device.

Fig. 2 is a vertical transverse sectional view through a portion thereof.

Fig. 3 is a horizontal longitudinal sectional view through one of the adjustable supports in its outstretched arrangement.

Fig. 4 is a side elevation thereof when folded, and

Fig. 5 is a vertical transverse sectional view of the support taken upon line VV of Fig. 4. I

My device may be readily positioned upon any boat for protecting the same and is herein illustrated in connection with a ship 10 having a hull 11 provided with a deck 12 upon which two upright masts 13 are fixedly mounted.

A metallic net or screen 14; is arranged in the water such as 15 upon a plurality of floats 16, the said screen being attached by means of cables 17 with outstretched telescoping supporting poles 18 carried by the deck 12.

A bracket 19 is arranged for each of the poles 18 providing a platform 20 with which the inner section 21 of the pole has slidable dove-tail engagement as at 22. Each ofthe outer sections 23 of the pole 18 is arranged in telescopic relations with one of the cables 17 attached to the outermost section 24 having the smallest diameter of any of the sections. All of the pole sections are of substantially the same length and all of the same are hollow excepting the outermost section 24, a guide opening 25 being arranged, however, in the pole section 26 positioned adjacent the outermost section 24:.

A guy wire or line 27 is connected adjacent the forward end of each of the pole sections and to the top of the adjacent mast 13 as at 28 for assisting in supporting the pole 18 horizontal when in its outstretched operative position. A similar" guy wire 29 connects the bracket 19 with the adjacent mast 13 as at 30. When the pole :18 is outstretched, a rod 31 is adapted to be thrust axially therethrough in contact with the inner end of the outermost section 24 and extending through the gnideopening 25 and the adjacent sections of the pole while a stop 32 is adapted to engage the inner end of the rod 31 for maintaining the rod in position with the pole sections outstretched. The stop 32 is in the form of a screw threaded through the inner side member 33 of the bracket 19 and may be adjusted for outwardly forcing the rod 31' to thereby substantially rigidly position therod within the adjacent pole. The stop'may be retracted when desired for permittingthe rod 31 to be readily removed.

Side racks 34 are provided for the inner pole section21 with which pinions 35 carried by the said bracket are in constant mesh. By the employment of a crank 36 upon the squared axle 37 of either of the pinions 35, such pinion may be turned for moving the inner section21 either inwardly Or outwardly as is desired, it being understood that the rod 31 is removed-prior to such operation. By pulling upon any of the guy wires 27, the sections of the pole 18 may be drawn inwardly until all of the sections are nested within the inner section 21 which may be retracted by the pinions 35 and this inoperative position of the pole is illustrated in Fig. 4 of the drawings.

It will be seen that when the screen 14 is not desired for use, all of the poles 18 are retracted which brings the screen as Well as the floats 16 inwardly substantially in contact with the hull 11 while the screen may be readily projected outwardly a considerable distance from the hull and retained in position by the rods 31 with their stops 82. A plurality of weights 38 are arranged for the screen ll for maintaining the screen in a substantially vertical position within the water. A torpedo approaching the hull 11 beneath the surface of the water will come in contact with the screen 1 t which will gradually stop the forward progress of the torpedo without exploding the same before the torpedo comes in contact with the hull of the ship, thereby preventing any injury to the ship. Vi hen the device is not desired for use the same may be folded in its inwardly arranged position and at which times it will present very little obstruction to the travel of the ship through the water.

hat I claim as new is 1. In combination with the hull of a ship, mounting brackets arranged upon the deck thereof, inner pole sections having slidable dove-tailed engagement with the said brackets, operating means for the said dove-tailed sections, outer pole sections telescopically connected with the said inner sections and a missile screen suspended from the outermost pole sections.

2. In combination with the hull of a ship, mounting brackets arranged upon the deck thereof, inner pole sections having slidable dove-tailed engagement with the said brackets, operating means for the said dove-tailed sections, outer pole sections telescopically connected. with the said inner sections, rods axially arranged through the said poles in contact with the outermost sections thereof adjustable stops carried by said brackets in contact with the inner ends of the said rods and supporting guy ropes for each of the pole sections.

3. In combination with the hull of a ship, mounting brackets arranged upon the deck thereof, inner pole sections having slidable dove-tailed engagement with the said brackets, operating means for the said clove-tailed sections, telescoping outer pole sections, a missile screen arranged in the water surrounding the hull of the ship, weights upon the lower edge of the screen, floats upon the upper edge of the screen adapted for positioning upon the water, connections between the upper edge of the screen and the outermost sections of said poles and means adapted for maintaining the poles in their outstretched arrangen'ient.

4. A support for rotecting screens comprising a bracket having a platfori'n, a tubular pole section longitudinally slidably arranged in dove-tailed connection with the said platform, side racks carried by the said pole section, pinions journaled in the said brackets in constant mesh with the said racks, operating means for the said pinions and a plurality of outwardly positionable pole sections arranged in telescoping relati on with the said inner section.

5. A support for protecting screens comprising a bracket having a platform, a tubular pole section longitudinally slidably arranged in dove-tailed connection with the said platform, side racks carried by the said pole section, pinions journaled in the said bracket in constant mesh with the said racks, operating means for the said pinions, a plurality of outwardly positionable pole sec- 'tions arranged in telescoping relation with the said inner section, the outermost pole section being of solid formation and the other pole sections being tubular in form, a positioning rod axially arranged through all of the said sections excepting the outermost section and in abutting engagement with the inner end of the latter when operatively arranged and an adjustable stop carried by said bracket in contact with the inner end of said red when the device is assembled with the pole in its open outstretched position In testimony whereof I affix my signature.
